My great-great grandmother was Dutch I believe, I cannot read her daughter's handwriting very well (the information I have is via her records), but her first name appears to be:
Madalence, the rest is clearer: Johanna Verwagen.
I've no idea which region she was born in, but she spent a large part of her life in the West Indies. Her married name was Weber (don't have any more information on her husband), and she lived in what was then called British Guiana. Her daughter Florence Marie Weber married my great-grandfather Dr George Herbert Kemp Ross in 1899.
I do have 2 photos of M. Johanna Verwagen, in her middle-age which I can email to anyone who thinks they might be able to help.
Kind regards
